Brian - 1 - yes, routing is not an option for most cases. 2 - yes, GridFTP will always keep routing data via private, while auth and 3rd party client keeps getting transfer stat updates via public. (For me - yes, acceptable. Maybe there are more use cases?) Andrew - If hosts behind NAT, not an issue, then yes - the host making a connection to the control channel will be the same asking for data channel. For DNS - Usually no, there are no entries in DNS of our servers - So it will not resolve. -- You are receiving this because you are subscribed to this thread.
